中文摘要:
      研究了一种生物基三元聚酰胺共聚物在Hanks缓冲溶液、盐酸和氢氧化钠溶液中的降解行为。通过傅里叶变换红外光谱、热重分析、扫描电子显微镜、离子色谱等手段对其降解前后物质的微观形貌和结构进行了详细分析,并研究其水解机理。结果表明,该生物基聚酰胺在3种溶液中均发生降解,且在氢氧化钠中降解速率最快,5周后质量损失达50%。
英文摘要:
      In this research, the degradation of ternary polyamide polymer was studied and the hydrolysis mechanism of the polymer was investigated by Fourier infrared spectrum (FT-IR), thermogravimetric analyzer (TG), scanning electron microscope (SEM) and ion chromatography (HPIC). The results show the ternary polyamide degrades in hydrochloric acid, Hanks buffer solution and sodium hydroxide solution. It is found that the degradation rate in sodium hydroxide solution is the fastest among these three solutions.After five weeks of degradation, the mass loss rate is 50%.
